1. solar energy heating can not only store one day's heat energy like ordinary heating, but also store one week's solar energy, and even realize inter-season energy storage, storing solar energy in spring, summer and autumn for heating season.
2. The shape of the collector can be designed according to the surrounding environment, so that the whole environment can be coordinated and balanced. And the collector can be placed vertically, which can not only avoid overheating in summer, but also provide heating in winter.
3. The water tank can be installed underground, which saves ground space and is not affected by underground humidity and rainwater intrusion.
4. solar energy heating can be combined with auxiliary energy sources, including oil-fired boilers, gas stoves, biomass boilers, coal-fired boilers, electric heating and heat pumps. To meet your heating needs to the greatest extent.
5. Energy conservation and environmental protection can be said to be the biggest advantage of solar energy heating. During the non-heating period, hot water can be supplied. During the heating period, compared with other heating equipment, which costs hundreds of yuan per month for heating, electricity and gas, solar heating has unparalleled energy saving, and will not produce carbon dioxide, carbon monoxide and other waste gases, which is very environmentally friendly and safe.
6. Solar heating has high efficiency, long service life, fast heating speed and high temperature, which can increase the surface temperature of radiator by at least 90℃ in a few minutes. Life is longer than ordinary heaters, up to 50 years.
Disadvantages of solar heating: solar heating has high requirements for buildings, requiring buildings to face south, and there should be enough area on the surface or next to buildings to place collectors, and the glass of buildings should be energy-saving.
Solar heating system requires high materials, and pipes and fittings are required to have the characteristics of high temperature resistance, heat preservation, corrosion resistance and flame retardancy.
The thermal resistance of solar heating to the ground should be less than 0.05 ㎡℃/w, and wooden floors and blankets should not be used. It is required that the width of ground expansion joint is greater than 20mm and the thickness of filling layer is greater than 50 mm.
